Never tried solving such problem. IMHO, The best way is to reflash your system.

If you don't want to do it for whatever reason, you can try the following option if you feel safe. Be warned. I can't guarantee anything safety. Do it on you own risk.
Re-create the structure of /mnt. The directory under /mnt are: "share", "free", "temp", "protected", "settings", "cf", "card", "net", "usb" and "ram". These directories are mount points of certain filesystems.
